History of Tempered Glass
The development of tempered glass dates back to the mid-17th century, and one of the princes of the Rhine, Robert, has done an interesting experiment. He put a drop of molten glass in icy water and made a Extremely hard glass. This kind of high-strength granular glass is like water droplets, dragging long and curved tails, called "the prince of Robert". But when the tail of the small particles is bent and broken, it is strange that the whole small particles so suddenly violent collapse, and even became a fine powder. The above practice, much like metal quenching, and this is the glass quenching. This quenching does not make any change in the composition of the glass, so it is called physical quenching, so tempered glass tempered glass, also known as quenched glass. The first patent for glass glazing was obtained by the French in 1874, where the glass was heated to near the softening temperature and immediately put into a relatively low temperature liquid tank to increase the surface stress. This method is the early liquid steel method. Germany's Frederick Siemens in 1875 received a patent, the United States Massachusetts Geovge E.Rogens in 1876 will be applied to the glass method of glass and lamppost. In the same year, HughO'heill of New Jersey won a patent.

In the 1930s, Saint-Gobain and the United States of America Treprex, as well as the British company Pilkington began to produce large-scale flat tempered glass for automotive use. Japan in the 20th century, 30 years have also carried out the production of glass industry. From the world began a large-scale production of tempered glass era.

After 1970, the British Triplex company with liquid medium steel thickness of 0.75 ~ 1.5mm glass to be successful, the end of the physical steel can not be tempered glass history, which is a major breakthrough in glass technology.

China's history of glass began in 1955, Shanghai Yaohua glass factory began trial production, in 1958 Qinhuangdao City, glass factory trial production success. 1965 Qinhuangdao Yaohua glass factory began to produce military use of tempered glass, the 20th century, 70 years, the first introduction of Luoyang glass factory in Belgium steel equipment. Shenyang glass factory chemical glass production in the same period.

The 20th century, 70 years began to strengthen the glass technology in the world has been a comprehensive promotion and popularization, tempered glass in the automotive, construction, aviation, electronics and other fields began to use, especially in the construction and automotive development of the fastest.
